A beggar, like the ones in big cities that ask for change, but instead of change, he wants cum shots. Therefore, he is the "Cum Bum."
Man: "I was walking down Jefferson in Chicago, and I saw this guy coming up to me. I thought he was gonna ask me for some change, but he wanted my semen. Isn't that gross??"
Other Man: "Yeah dude, that's fucking sick. He's the Cum Bum!!"
